Physiological Studies On Growth Development And Yield Component Of Basmati RiceUnder Different Planting Times

Abstract

The field experiment was conducted atStudent s Instructional Farm, ofChandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.), during two kharifseasonsi.e.2016 and 2017.The objectives of investigation was Physiological studies on growth, development and yield component of Basmati rice under different planting times . morphological, physiological, phenological, biochemical, yield and its components of four basmati rice varieties under three date of transplanting. It was designed in split-plot design with three replication, The three dates of transplanting with., first date of transplanting02thJuly (D1), yield decreasing, trained in second date of transplanting16thJuly(D2),and third transplanting30thJuly(D3),conditions were allocated in the main plots and four basmati rice varieties PB-1 (V1), PB-1509 (V2), PB-6 (V3), and PB-1121(V4), in sub plot. The significantly higher grain yield kg/ha,first date of transplanting02thJuly (D1),3893and 4329 kg/ha, followed by second date of transplanting16thJuly(D2),3430 and 3867 kg/haand minimum third date of transplanting 30thJuly(D3),3224 and 3645 kg/ha, with best morpho-physiological, phonological,(temperature) and biochemical traits, can be obtained first transplanting dates, and higher grain yield kg/ha, both year of experimentation respectively. The significantly higher grain yield kg/hain variety PB-1509 (V2) 3918 and 4306 kg/ha, followed by varietyPB-1121(V4)3597 and 4060kg/ha, and minimum invariety PB-6 (V3) 3158 and 3612kg/ha, with the both year 2016 and 2017, respectively. newlineTraits like number of tiller (0.845**and 0.799**), leaf area index (0.915**and 0.937**), number of panicle (0.933**and 0.920**),test weight (0.760** and 0.724**)and harvest index (0.866**and 0.852**) can be used to higher grain yield, they showed significantly higher positive correlation with grain yield during in both year of experimentation 2016 and 2017respectively newline newline
